Azurewave AW-CM276NF Wi-Fi & Bluetooth module
Introductionβ
The AW-CM276NF is a Wi-Fi & Bluetooth M.2 LGA Type 1216 module. The device is based on the NXP 88W8997 (formerly Marvell 88W8997) chipset and implements the same reference design. For more information about compatible setups please check AW-CM276NF - Azurewave peripheral database.
How to get startedβ
We have a step by step Getting Started Guide for the following modules:
- Colibri iMX6ULL - Basic Wi-Fi usage
- Colibri iMX8X - Basic Wi-Fi usage with Torizon
- Apalis iMX8 - Basic Wi-Fi usage with Torizon
- Verdin iMX8M Mini - Basic Wi-Fi usage with Torizon
After following the step-by-step guide above, you can visit our article WiFi Support on Toradexβs Linux Images with complementary information.
Embedded Linux - Software Support Statusβ
The on-SoM Wi-Fi module has a device driver and corresponding firmware included in our BSP Layers and Reference Images for Yocto Project as well as Torizon OS by default.
- The device driver included in BSP 5 is the Marvell WiFi-Ex driver from Mainline Linux kernel, along with its corresponding firmware.
- Some use cases - such as Wi-Fi client mode + Bluetooth - don't work with this driver. If your use case does not work, please contact our support, as we are doing some tests with the downstream NXP drivers and they seem to work well for some use cases that are not supported by the mainline driver.
Certification documents for Azurewave AW-CM276NF Wi-Fi / Bluetooth moduleβ
For information about Certification, please refer to Certification documents for Azurewave AW-CM276NF Wi-Fi / Bluetooth module.
Often, to certify your final product, the regulatory agency will require that you configure the Wi-Fi module in a manufacturing mode. This is only possible with the NXP driver. We are working on documenting it, meanwhile contact our support to learn more.
Wi-Fi certification on Wi-Fi accessories recommended for Toradex modulesβ
For information about RF cables and antennas certification, please refer to Wi-Fi certification on Wi-Fi accessories recommended for Toradex modules.
Radio Frequency Calibration Dataβ
The AW-CM276NF has been calibrated before shipment, and the data has been recorded in the module's OTP memory. That way, it's not necessary to set any calibration data when using it.

- IEEE 802.11i for advanced security
- Quality of Service (QoS) support for multimedia applications
- AP mode (access point) supported, limited by 8 simultaneous connections to the device
Known limitationsβ
Since AW-CM276NF's chipset (NXP 88W8997) is single-mac, it is limited to work on only one channel. It is possible to have access point (AP) and station (STA) working concurrently, but both must be using the same channel being it in 2.4GHz or 5GHz.
Trying to force different channels will cause the wireless interfaces to behave unexpectedly e.g. it might advertise wrong information about the connection (e.g. wrong channel).
To know how to configure STA and/or AP, please check the How to get started section in this article.
